<u>Answer:</u>
Mrs. Khan is mailing 2 packages. Subtract 623 – 312 best describe how to find out how much heavier the larger package is. Hence Option C is correct
<u>Solution:</u>
Given that
Mrs khan is mailing two packages.
Weight of larger package = 623 pounds
Weight of small package = 312 pounds
Now we need to find how much heavier larger package compare to smaller one is.
To get this if we remove weight of smaller package from larger package , we will get how much larger package is heavier.
That is<em> Weight of larger package – Weight of smaller package</em> = 623 pounds – 312 pounds
Hence option C) subtract 623 – 312 best describe how to find out how much heavier the larger package is.
The only set of elements that satisfied the equation 2x-1= -13 is {-6}.
<h3>What is a set?</h3>
A set is a combination of specific quantities in which the meaning of each variable must be the same.
For example {1,2,3,4,5,6...} is a set of natural numbers in which each variable is representing a natural number so the overall meaning is the same among all.
Another example could be a set of whole numbers like that.
Given the equation,
2x-1= -13
By taking -1 right-hand side
2x = -13 + 1 = -12
By dividing 2
x = -6
Hence "The only set of elements that satisfied the equation 2x-1= -13 is {-6}".

Answer:
12 gallons
Step-by-step explanation:
If it takes 20 h for 5 gallons to be filled, it takes 4 h for 1 gallon to be filled. This is the ratio. You multiply 4 h by 12 to get 48 h, so you multiply 1 gallon by 12 as well. This is 12 gallons.
This is the concept of algebra, the percentage of Milk in the 4 cup mixture will be found as follows;
the ratio of milk to mixture after 1 cup was added to 3-cups was:
1/3
the total ratio of milk in the mixture was:
1/3+3/5
=14/15
thus the percentage of milk will be:
14/15*100
=93 1/3%
